如何在Ubuntu上安装OpenSSL库?

我试图在使用OpenSSL 1.0.0的Ubuntu 10.04 LTS上构建一些代码。当我运行make时，它使用“-lssl”选项调用g++。资料来源包括:

#include <openssl/bio.h>
#include <openssl/buffer.h>
#include <openssl/des.h>
#include <openssl/evp.h>
#include <openssl/pem.h>
#include <openssl/rsa.h>

我跑:

$ sudo apt-get install openssl
Reading package lists... Done
Building dependency tree       
Reading state information... Done
openssl is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

但是我猜openssl包不包括这个库。我在make时得到这些错误:

foo.cpp:21:25: error: openssl/bio.h: No such file or directory
foo.cpp:22:28: error: openssl/buffer.h: No such file or directory
foo.cpp:23:25: error: openssl/des.h: No such file or directory
foo.cpp:24:25: error: openssl/evp.h: No such file or directory
foo.cpp:25:25: error: openssl/pem.h: No such file or directory
foo.cpp:26:25: error: openssl/rsa.h: No such file or directory

如何在Ubuntu 10.04 LTS上安装OpenSSL c++库?

我为-l选项做了一个man g++和(在“链接选项”下)，它声明:“链接器为库搜索一个标准目录列表…”和“搜索的目录包括几个标准系统目录…”这些标准系统目录是什么?

当前回答

另一种在Ubuntu上从源代码安装openssl库的方法如下，这里WORKDIR是你的工作目录:

sudo apt-get install pkg-config
cd WORKDIR
git clone https://github.com/openssl/openssl.git
cd openssl
./config
make
sudo make install
# Open file /etc/ld.so.conf, add a new line: "/usr/local/lib" at EOF
sudo ldconfig

其他回答

一般来说，当你在Debian或Ubuntu上丢失了一个开发文件(或任何其他文件)时，使用apt-file来找出哪个包提供了该文件:

~ apt-file search openssl/bio.h
android-libboringssl-dev: /usr/include/android/openssl/bio.h
libssl-dev: /usr/include/openssl/bio.h
libwolfssl-dev: /usr/include/cyassl/openssl/bio.h
libwolfssl-dev: /usr/include/wolfssl/openssl/bio.h

快速浏览命令返回的每个包，使用apt show将告诉您在这些包中寻找哪个包:

~ apt show libssl-dev

所有这些答案都是非常过时的，来自于软件包仍在开发的时候。你现在可以使用下面列出的"normal"命令:
